Car Ezra avait disposé son cœur à étudier la doctrine de l’Éternel et à la pratiquer, de même qu’à enseigner dans Israël la loi et le droit.
Avot D'Rabbi Natan
Make your Torah study a fixed practice. How so? This teaches us that if a person hears advice from the mouth of a sage in the study hall, he should not make it an occasional practice but a fixed practice. What a person learns, he should do, and then teach others, and they should do, as it says (Deuteronomy 5:1), “Learn them, and take care to do them.” And also in Ezra it says (7:10), “For Ezra had prepared his heart to seek the Torah of the Eternal and to do it.” And after that, it says, “and to teach Israel rules and laws.”
